The objective is to improve the ease, cost, and efficiency of using splints to treat patients with musculoskeletal disorders. Splints are commonly used to treat sprains, fractures, muscle contraction, and spasticity. Low-temperature thermoformable (LTT) in situ to address patient treatment needs. Currently, because of relatively low strength and stiffness. LTT splint materials are only used in low load-bearing applications. High load-bearing splint applications require high- temperature then plastics or thermoset materials. High-temperature thermoplastics cannot be formed in situ and therefore are molded by trail and error to fit to patient. Thermoset materials can be molded in situ, but cannot be reshaped to optimize the fit. These limitations suggest that there is a need for-low-temperature thermoformable material that will mold directly on the patient, reshape to optimize fit, and provide the stiffness and strength required to treat high load-bearing applications. The goal to develop a fiber-reinforced LTT splint material with high strength and rigidity evaluating the strength, stiffness, and thermoformability of various fiber/matrix laminate architectures. The results will determine the feasibility of producing how strength and stiffness fiber-reinforced LTT composite materials and the potential for these materials to be used in clinical splinting applications.

目标是提高使用的便利性、成本和效率 用于治疗肌肉骨骼疾病患者的夹板。夹板是 常用于治疗扭伤、骨折、肌肉收缩等 痉挛。原位低温热成型 (LTT) 可解决 患者的治疗需求。目前由于实力相对较低 和刚度。 LTT夹板材料仅用于低承重 应用程序。 高承载夹板应用需要高 温度高于塑料或热固性材料。高温 热塑性塑料无法现场成型，因此需要通过试模成型 和适合患者的错误。 热固性材料可现场成型， 但无法重塑形状以优化贴合度。这些限制表明 需要一种可低温热成型的材料 将直接在患者身上成型，重塑以优化贴合，并提供 处理高承载所需的刚度和强度 应用程序。开发纤维增强LTT夹板材料的目标 具有高强度和刚度评估强度、刚度和 各种纤维/基体层压结构的热成型性。这 结果将决定生产强度和可行性 纤维增强 LTT 复合材料的刚度及其潜力 这些材料用于临床夹板应用。
