The thermoplastic textile-reinforced composite, known as Twintex, is investigated. Material Twintex is a woven fiberglass fabric with polypropylene fibers. The samples from this material for tensile tests according to ISO 527-4 were made by autoclave molding and then cut through water jet cutting. The samples were exposed to a hydraulic fluid AMG10 and seawater for 120 hours and then tested in accordance with the tensile standard at temperatures 273-373K. The change of elasticity modulus and strength of investigated material in considered conditions was measured. The experimental values of strength limits and elasticity modulus of investigated material at different temperatures after the influence of liquids have been obtained. Degradation of specified properties is observed depending on temperature and time of exposure comparing to the initial one. Using data of previous studies, degraded values of mechanical properties of material at various temperatures were calculated. Additionally, a change of mechanical properties of material from the temperature is taken into account. Experimental and estimated data were compared: difference between experimental and theoretical data is 6%.
